What are the characteristics of clay soil?

Considered ungrateful by many amateur gardeners, it must be admitted that the clay soil is not the easiest to cultivate. It does not work well, weighed down by the many rock particles of which it is composed. When wet it becomes very compact, which prevents air from circulating properly: suddenly the roots suffocate, the plants are asphyxiated. The clay soil hardly heats up in spring, in summer when the rain is scarce, it becomes hard and cracks. When it rains a lot, it is sticky and water can hardly penetrate it. This is why it is essential to drain it in order to limit puddles. It is not recommended for frostbite plants because the gel penetrates into the clay soil.

Besides these uninviting peculiarities, does clay soil have advantages?

The clay soil does not have only faults! It is an extremely fertile soil: which is an undeniable advantage. Fortunately, moreover, because in France clay soil is widely present in all regions.

Is clay soil recommended for potted plants?

This type of substrate is never recommended for potted plants if used as is. You can lighten the clay soil by mixing it with potting soil and why not add a little river sand.

Place a drainage bed at the bottom of the pot - such as gravel or clay balls for example - and cover it with the substrate that you have prepared.
